Enhanced neutrino signals from dark matter annihilation in the Sun via metastable mediators
Nicole F. Bell, Kalliopi Petraki
We calculate the neutrino signal resulting from annihilation of secluded dark matter in the Sun. In this class of models, dark matter annihilates first into metastable mediators, w…

Small-scale structure formation properties of chilled sterile neutrinos as dark matter
Kalliopi Petraki
We calculate the free-streaming length and the phase space density of dark-matter sterile neutrinos produced from decays, at the electroweak scale, of a gauge singlet in the Higgs…

Dark-matter sterile neutrinos in models with a gauge singlet in the Higgs sector
Kalliopi Petraki, Alexander Kusenko
Sterile neutrino with mass of several keV can be the cosmological dark matter, can explain the observed velocities of pulsars, and can play an important role in the formation of th…
